Hi everybody,

I'm trying to stream in h264 from a DV camera.
I've wrote some modifications for h264 streaming and it work well for a
plain file.

But now I want to do it in live. I'm running FreeBSD, my DV cam is plugged
in firewire and I can get DV stream with fwcontrol.
I've modify testOnDemandRTSPServer for using my h264 implementation, and to
make it read from stdin
So I try something like that : *fwcontrol -M dv -R - | ffmpeg -i - -vcodec
libx264 -r 12 -s cif -flags2 aud -an -f h264 - | ./testOnDemandRTSPServer*
When VLC start to play, ffmpeg start to encode but even after a while, no
video appears.

ffmpeg start to encode with a bunch of this error:
*AC EOB marker is absent pos=89
AC EOB marker is absent pos=68
AC EOB marker is absent pos=65
AC EOB marker is absent pos=64
AC EOB marker is absent pos=107
AC EOB marker is absent pos=64
AC EOB marker is absent pos=65
AC EOB marker is absent pos=64
Last message repeated 2 times*
and I don't know the meaning of this messages.

So my question is how I can feed my RTSP server to stream in live from my dv
cam?

Thanks in advance.
